Biography of Tamil Nadu activist Arunachalam Muruganantham, whose mission was to provide sanitary napkins to poor women of rural areas who used rags or leaves because sanitary napkins were rare. After he did not get fruitful results from his family and a medical college he approached, he decided to try it himself by filling a football bladder with goat's blood and roaming around with it for a day to check the absorption rate of the sanitary napkins he made.
